Question

A trader is offered a discount of 15% by one wholesaler while he is offered a discount of 12% and a further cash discount of 3% by another find which is cheaper if at all if he purchase at the cheaper rate and sales at 5% below list what rate per cent profit does he earn on his CP and SP?​

Answer 1

Answer:

the OA is (C)

The "trick" is to find the original cost ---> C

80-Cost = Profit

P/C = 20/100

(80-C)/C = 20/100

80-C = 1/5*C

80 = 1/5*C+C

80 = 6/5*C

400 = 6*C

C = ~67

hence ---> 100-67=33 ---> 33/67 = ~50
